BRAKE-HANGER SUPPORT.

Application filed January 10, 1927.

My invention relates to means for supporting the hangers which pendently hold the brake beams in place from the truck side frame. Truck side frames as at present more generally employed comprise a one piece structure of cast or pressed steel. With my invention, the side frames on the inner sides thereof, adjacent to the vertical members of the side frame, are provided with laterally disposed arms of predetermined length having flanges arranged in vertically spaced relation and preferably connected adjacent the ends to provide a socket or pocket therebetween adapted to receive a pin supporting and thrust receiving means adapted to be removably secured in the socket or pocket in a manner which will permit its ready removal and the replacement of parts when desired in order that the support may be adapted to the Ushape link type othanger as well as to the continuous link type of hanger.

The invention also involves a construction wherein the hanger supporting pin, where the U-shape type of hanger is employed, may be reversed relative to its ends so that any wear on the supporting pin may be transferred to other portions thereof and the life of the supportingmeans thus enhanced; while at the same time providing a structure wherein loss of parts when properly assembled is impossible.

The above enumerated objects and advantages, as well as others inherent in the invention, will be more readily comprehended from the detailed description of the accompanying drawings, wherein Figure 1 is a side elevation of one end or portion of a truck side frame, showing in dotted lines the position of my improved hanger supporting means.

Figure 2 is a vertical sectional elevation as viewed substantially on the line 2-2 of Figure 1 looking in the direction of the arrows.

the use of the U-shape type of hanger as employed in Figure 2.

Figure 9 is a detail perspective View, looking upwardly, of the retainer element employed with the construction shown in Figure 5.

The invention has for its object the pro vision of means whereby the supporting links, whether of the U-shape or continuous link type may not only be securely held in place and all wear taken up by the keeper or retainer element, but the assembly and positioning of the various elements readily made and obtained, while at the same time permitting a substitution of the one type of supporting hanger for the other without necessitating alteration in the portions integral with the truck side frame.

In Figures 2 to 4:, I illustrate my improved means used in connection with the U-shape type of hanger or link, a portion of the side frame being shown at 15. The inner side of the side frame, namely the side disposed toward the wheels of the truck and adjacent to the vertical portions or compression members of the side frame is provided with an integral transversely disposed arm or projecting portion 16 having at its top the flange portion 17, the outer end whereof is shown provided with an integral vertically disposed flange portion 18 extending downwardly and preferably connecting with the laterally disposed flange portion 19. The flange portion 19 is shown provided with a reinforcing rib 20 formed integral with the arm 16 secured to the side frame. In alignment with the flange portion 19, I provide a laterally disposed flange portion 21, which likewise is preferably provided with the reenforcing ribs 22; and in spaced relation and in horizontal alignment with the flange portion 21; I provide the flange portion 23 made preferably with the angular or off-set end flange portion 24 which also connects with the upper flange portion 17 at a point slightly removed from the side frame proper. The end flange portion 241 is offset or of the irregular angular construction shown in Figure 2 to provide a pocket or socket as at and with end flange 18 provides a closure for the hanger supporting pin. The various flange portions 19, 21 and 23 are not only in predetermined horizontal spaced relation, but are arranged in vertical spaced relation with the top flange portion 17 and are all of suflicient transverse dimensions to provide a suitable pocket or enclosure adapted to receive a block like retainer or keeper and wear-receiving ele ment 26 which is preferably of the rectangular formation more clearly disclosed in Figure 4. The flange portions 19, 21 and 23 are spaced apart a sulflcien't distance to provide slots through which the hanger 27 depends. The hanger 27 as employed in Figures 2 to 4, is of the tl-shape type with the upper ends enlarged or eyeletted as shown at 28 in Figure 3 to receive the supporting pin 29, which latter preferably extends substantially from end wall or flange 18 to the offset end wall or flange portion 24, see Figures 2 and 4, in order that longitudinal movement I of the pin will not take place.

The keeper element or retainer 26 is in the nature of a rectangular block which, for the sake of lightness is cut away or cored, as shown at 30 and 31. The depth of the pocket between flange portions 17, 19, 21 and 23 and the transverse dimensions of the keeper element are such that the forward face of the keeper element will extend sul stantially flush with the forward edges of the flange portions. The top and bottom flange portions 17 and 21, as well as the keeper element 26, are shown provided with ears or extensions 17, 21 and 26 respectively, which are apertured to receive the keeper retaining bolt 32, held in place by nut 32, while the bolt is held against rotation by having its head in abutting relation with an upstanding lug 33 formed on the top flange 17, see Figure 3.

The keeper element is preferably formed so as to contact at its ends with the end flanges or walls 13 and 2t, by reason of the boss formations 3 1, 3 1, see Figures 2 and The keeper block 26 is provided with an opening extending longitudinally therethrough as well through the boss formation 34, 34, to receive the supporting pin 29; the boss formations or enlargements 3 1 thus also providing a greater bearing surface for the ends of the pin 29.

The keeper block 26 is provided with transversely extending sockets 35, 35, open at bottom and at the front face of the block in order to receive the enlarged eyeletted ends 28 of the hanger or link 27 and permit free oscillatory movement of the latter; the link depending through the open bottom of the sockets 35, 35.

In practice, the upper ends of the link 2'? are inserted into the keeper block 26 and the supporting pin 29 then inserted endwise through the hole in the block and through the eyes of the link; the block or keeper element 26 is then inserted into the pocket formed between the spaced parallel flange portions, after which the locking bolt 32 is inserted in place. It is apparent from this construction that the upward and downward thrusts of the hanger or link 27 are entirely transmitted to the keeper block through the pin 29 and therefore any wear encountered will be on parts which may be readily removed and replaced, namely the pin 29 and the keeper block 26 and no wear on parts formed integral. with the truck side frame can take place. This is quite an important feature and eliminates the excessive cost of side frame repair and replacement.

in Figures 5 to 9, T illustrate a modified form of my invention, wherein the supporting means is adapted to both the U-shaped type and to the continuous link type of hanger.

The truck side frame 15, like that in the previously described figures, is provided with an integral arm or projection 16, having the top and bottom flange portions 17, 19, 21 and 23; with the top flange portion 17 being connected at its end with the bottom flange portion 19 by means of the vertical end flange portion 18 and said top flangt portion also having the end forming flange portion 23 connected therewith; the flange portion 23 having the intermediate offset 24 to provide a socket for one end of the supporting pin 29 when the U-shape type 01 hanger is employed.

The arm or projection 16 in the construction shown in Figures 5 to 8, at an interme diate point, has its vertical wall provided with a forwardly presented lug 36 formed integral therewith and disposed at a pointintermediate of the top flange portion 17 and the bottom flange portion 21, see Figure 6. The forward end of the lug 36 is undercut or formed arcuate as shown at 37 to leave an overhanging lip 37, in order to conform with the curvature of the upper end of the link hanger 38 or of the supporting pin 29 when the latter is en'iployed; F igures 5, 6 and 7 illustrating the use of the continuous link type of hanger. The retainer or keeper element 39, employed with this construction, is likewise of the more or less rectangular block form shown in Figure 9, being cored or cut away adjacent to the ends and from the bottom thereof as shown at 40 in Figure 9 to provide a passage for the insertion of the upper end of the link or hanger; the cored or cutaway portion also extending longitudinally of the lit keeper element adjacent to the rear or inner wall 41 of said element and thus leaving the intermediate elongated lug 42 at the forward or outer side of the keeper element. The intermediate boss or lug 42 is cored out or cut away to leave the end portions or transversely extending ribs 43 shown in dotted lines in Figure 6 above the passage 40 adjacent the rear wall of the lug 42; and the lug 42 is cored longitudinally to provide a pin or link-receiving socket 44 which com- 'municates above the bottom of the socket with the rear part of passage 40, thus leaving the upstanding lip 44. The end walls of the retainer element orkeeper are apertured at 45 in alignment with the socket 44 in order that a supporting pin, like that shown at 29 in Figure 8, may be disposed through the end walls of the keeper element 39 with one end of the pin entering the socket 24 formed in one end of the pocket in arm 16. The rear wall 41 of the retainer or keeper element 39 is provided with an opening 46 for passage of the boss or lug 36 therethrough; the opening 46 communicating with the slot or passage 40. The forward end of the boss or lug 36 is adapted to abut against the intermediate lug 42 of the keeper element; its undercut forward side, in conjunction with the socket portion 44 on the rear side of the intermediate lug 42, constituting complementary socke forming elements to receive the upper end of the supporting link 38 or the supporting pin 29 when the U-shape type of hanger 27 is employed. The boss or lug 36 extends intermediate of the ribs 43 of the keeper element 39.

The keeper element 39 is also shown provided with 'a vertically disposed aperture 47 extending through the forward side there of adapted to register with apertured extensions 1'7 and 21 of the pocket forming flange on the arm 16, to receive a suitable bolt 32 whereby the keeper element is secured in place.

As the retainer or keeper element 39, with its end wall bosses or enlargements 39 39" substantially fills the pocket formed on the arm 16 by the various flange portions and as the boss or lug 36 fits between the ribs 43, 43, it is apparent that the keeper element will be held in position against longitudinal movement, while the bolt 32 will. lock the same in place.

In practice, the upper end of the link hanger 88 is inserted through the passage 40 rearward of the intermediate lug 42 off the keeper element and placed in the passage 44 forward of the lip 44, after which the keeper element 39 with the suspended link is then inserted into the pocket formed in the arm 16; the sides of the link 38 depend-- ing through the vertically disposed portions of the passage 40 adjacent to opposite ends of the keeper element and between the lower flange portions 19 and 21 and between 21 and 23, thus allowing the link to have the necessary oscillatory movement. The link is held in the undercut socket 44 at the rear side of the keeper element by the boss or lug 36 formed integral with or secured to the arm 16, as is apparent from Figure 6. It is evident that wear, due to the down thrusts encountered by the link, will be taken up by the keeper element which may be readily replaced if the wear becomes too pronounced, by simply removing bolt 32 which will permit the keeper element with the link to be withdrawn from the pocket in the arm 16.

WVhere it is desired to employ the U-shape type of hanger 27, the eyeletted upper ends of the link are passed into the cored portions or passage 40 on opposite sides of the intermediate lug 42, the supporting pin 29 then inserted endwise through the openings 45 in the ends of the keeper element, and through the eyeletted ends of the hanger 27; the pin having bearing at its ends in the enlarged end walls of the keeper element, in the undercut groove 44 at the rear of the intermediate lug 42 of the keeper element while one end of the pin will be seated in the oft-set end wall of the pocket. The keeper element with the suspended hanger is then inserted into the pocket formed in the arm 16 in the manner previously describe; in connection with the continuous link type.

With the pocket forming flange portion 23 having the ofiset formation shown in Figures 2 and 5, it is apparent that a longer supporting pin 29 may be employed than would. be the case if the flange portion 2 3 were vertically disposed throughout its entire length like the opposite end flange portion 18. The purpose in forming the end flange portion 23 as shown and described is to permit the use of a longer pin, in order that the worn portions of the pin, induced by the eyeletted ends of the hanger 27, may be shifted by removing the pin and reversing it end for end, which will cause different portions of the pin 29 to register with the eyeletted ends of the hanger 27 on opposite sides of keeper lug 42, thereby greatly enhancing the life of the construction.
